convergence slot in glmer?

Dear mixed modelers,

I am looking for a way to identify false convergence in models running 
in loops.
Warnings are : "In mer_finalize(ans) : false convergence (8)" but are 
not stored in any slot, which makes impossible their assignation to 
particular models in loops.

Did anybody already face this problem? Any advice will be appreciated.

Thank you very much.

Hi,

When I had similar problems with nls and non-converging models for
some steps in the loop, the only way I found was to use the tryCatch
function.

It was for errors, not warnings, but according to its help page it
seems possible to catch also warnings with this function. So it should
be possible to use it with lme also in your case...

Hope this helps,

Best regards,
